Yes — forever. The entire understand-loop (blocks, hover & drill-in, expand-to-discrete, linting, themes) is free, with up to 10 designs. We never charge you to learn.
Pro lifts the 10-design cap entirely and unlocks private designs, manufacturing-grade export (Gerber / BOM / pick-and-place), version history, and advanced checks — for when you're shipping real hardware.
On Hobby, designs are public — discoverable, like a public repo. Keeping designs private is a Pro feature, for when you need to hold work to yourself.
